Unlocking opportunities across borders
Global Mobility
Unlocking opportunities across borders
Global mobility – the movement of employees across borders for work presents organisations and individuals with opportunities but also significant challenges
These challenges span logistical, cultural, legal, and personal dimensions
One major hurdle is navigating the complex web of international tax laws and labour requirements
Each country has distinct compliance and reporting rules that can change frequently, making it difficult for businesses to keep up. Rules may be different depending on whether you have a traditional expat, an international local hire, a remote worker or a business traveller. Non-compliance with tax regulations can lead to penalties, legal issues, and reputational damage.
Another challenge is managing the costs associated with international assignments
Relocation expenses, tax equalisation, provision of mandatory pension and benefits together with managing global compliance and reporting can add up, but having the right global talent is critical to a company’s success and it’s important to plan and understand requirements upfront so companies can balance competitive packages to attract and retain talent with controlling costs.
Finally, administrative complexity is a key concern
Coordinating global payroll, benefits, and ensuring data privacy across different regions can overwhelm internal teams. Implementing effective tracking systems, communication processes, and leveraging technology is crucial to managing these challenges while ensuring a smooth experience for employees and the company alike.
I get my energy from helping clients solve their challenges in the simplest way possible whilst ensuring the organisation and their employees receive an exceptional experience.

UK employee tax compliance
The Issue
A manufacturing business in Spain won a UK contract. Their Spanish employees are required to travel to the UK to carry out relevant work-related duties as part of their role. While working here, employees receive company-funded accommodation and assistance with their transport costs. They continue to be paid via the Spanish payroll with no reporting being performed in the UK.
The Solution
We assisted the client with their UK compliance and provided following support:
1) Submission of a voluntary disclosure to HMRC to pay prior UK taxes.
2) Setting up of a modified payroll scheme for UK payroll reporting.
3) Setting up a of a Short-Term Business Visitor Agreement for their qualifying business travellers.
4) Reviewing and submitting A1 certificates proving Spanish social security contributions have been paid
5) Provision of UK tax return services
6) Assistance to set up assignment policies to assist with future assignments
The Outcome
The client is now fully UK compliant with appropriate actions taken from a UK perspective.
Ensuring Employee Benefit Parity in a Cross-Border Financial Sector Acquisition
The Issue
An organisation in the financial sector was acquiring a target in a number of European jurisdictions. As part of the deal, the acquiring organisation wanted to ensure that the employees being transferred were no worse off from a benefits package perspective.
The Solution
Our pensions and benefits expert was engaged to review the benefits package (including pension, medical, life and long-term disability, leave policy, sickness absence policy, wellbeing, etc.) in each location for both the acquirer and the target.
From this “side-by-side” summary, potential gaps at a country and an individual level were identified and our expert worked with the acquirer to propose a new package to discuss with the target, their legal counsel and the employee representatives.
The Outcome
The organisation was able to proactively recommend a package that would comply with relevant requirements (e.g. TUPE) but also understand the cost implications of such a package. This put them in a strong position to negotiate the final packages within defined financial boundaries. It also put them on the front foot in terms of communicating outcomes to employees in a positive and engaging way.
A US CFO working in the UK
The Issue
Many senior executives have complex cross border roles. Recently we advised an organisation within the hospitality business to ensure that their recently hired US CFO, who was required to spend 25% of their time working for one of the Group’s UK companies, was getting both the UK and US tax reporting right.
The Solution
Our Global Mobility experts reviewed both the UK and US position for the Group and the CFO and assisted with the following:
Preparing tax simulations for the CFO to show the net impact based on the interaction of their UK and US taxes.
Setting up of an appropriate UK payroll to pay UK taxes based on the extent of CFO’s UK duties.
Assisted with administration of both the UK and US payrolls for the CFO.
Assisted with keeping the CFO insured within the US social security scheme.
Supported the CFO with relevant UK/US registrations and filing of their UK and US returns to optimise their tax position and mitigate double taxation.
The Outcome
The group was able to plan for CFO’s UK role in advance to ensure they were aware of both UK and US compliance requirements for the business and the CFO, with appropriate steps taken to optimise the CFO’s tax position and manage any associated costs.
